The object of this invention is to provide an internal combustion motorof light weight in which an explosion will occur on every down stroke ofthe piston thereby producing an engine with a high horse power incomparison to its weight. These and other advantages will be discussedmore fully during the description of the drawings.

In the drawings; Fig. 1 represents a crosssectional view of the engine.Fig. 2 shows a sectional view as taken along the line II-II in Fig. 1.Fig. 3 is a plan view of the upper piston, seen in Fig. 1. Fig. 4 showsa sectional view of the hollow piston rod, piston 15 and valve, as takenalong the line IV-IV in Fig. 3. Fig. 5 is a cross-sectional view of amodified form of engine. Fig. 6 shows a sectional view of the engineseen in F ig. 5 and as taken along the line VI-VI, Fig. 5. Similarnumerals of reference indicate corresponding parts throughout all thefigures of the drawings.

In the drawings Figs. 1 and 2 are seen a pair of cylinders comprisingthe upper cylinder 10 and the lower cylinder 11 separated by thedivision wall 12. At 13 is seen a third but smaller cylinder having aport 14 near the top thereof connecting to the upper part of thecylinder 11. At the top side part of cylinder 13 is an intake port 15.Near the base of cylinder 10 is an elongated exhaust port 16 openinginto the exhaust pipe 17. The wall 18 separates the exhaust pipe 17 fromthe intake to heat the incoming gases as will be readily understood. At19 is seen the piston of the lower cylinder 11, while at 20 is thepiston of the upper cylinder 10; these two pistons are rigidly connectedby means of the centrally disposed hollow piston rod 21. The lowerportion of the rod 21 has a port 22 opening into the hollow piston rod21. At 23 is seen a nut screwed into a central threaded part of thewall12 and against a ring 24, which seals around the hollow piston rod 21passing through said wall 12. At 23 lower end of the hollow piston rod21 is suitably attached or rigidly aflixed tothe piston 19. The upperend of hollow piston rod 21 enlarges at 20 to form the upper piston andcontaining theball valve, seen in Figs. 3 and 4, 1

consisting of a. ball 25 which is sealed and held in place by a ring 26which is threaded and screwed into the piston 20 as disclosed This ringhas overlying fingers 27' which cover the ball 25 to retain the ball inits cage as in Fig. 4.

The piston 28 for the small cylinder 13 is provided with a connectingrod 28%, driven by the eccentric 29 as mounted on the crank shaft 30which has the usual bearing supports in the base of the motor. At .31 istheusual connecting-rod for the piston 19 andjdriven from the crankshaft 30 in the usual manner. The eccentric 29 is set a few degreesahead of the crank as shown by the X degrees, Fig.2.

-The engine operates as follows: ,On the down stroke of the pistons 19and 20, the .pis ton 28 also travels downwardly, but is ,setia littleinadvance of the pistons 19 and-20, or the X degrees previouslymentioned. Inthis downward travel, the piston 28 which on its up strokehas passed and sealedthe port 14 now passes the port 14 or so that theport 14' is opened to admit the charge of airand gas as received fromthe carburetor C through the port 15 and port 14 and into'the cylinder11. Upon the upstrok of the pistons, the port 14 is closed and thepiston20 in its upward travel closes the-exhaust port 16 and as thepistons 19 and 20 continue on their upward stroke the vapor in thecylinder 11 un; dergoes compression causing it to enter the hollowpiston rod21 through the port 22'to lift the ball 25 and discharge intothe cylinder 10 where the process of compression is con tinned. At theextreme upper positionofthe' pistons 19 and 20, thetop of the port 22regis ters a little above the nut 23 thereby releasing the pressure inthe cylinder 11 or sothat the ball 25 seatsits'elfthereby holding" thecompressed charge of gaseous vapors within the upper part of thecylinder 10. At this point combustion takes place andthe pistons 20and'19 are driven downwardly and-during this downward travel anew chargeof gaseous vapor is permitted to pass through the then opened port 14 tolater repeat the process of compression in the cylinder 10. When thepiston passes the exhaust port 16, the burnt gases, due to the expansionthat has taken place, exhaust through the port 16, there being then nopressure in the cylinder 10 and a partial vacuum being created new gasesmay then be introduced through the ball valve 25, As the pistons travelupwardly the process of compression and combustion is repeated Referringto Figs. 5 and 6; at seen the usual cylinder provided with a piston B;con

'necting rod D and crank shaft E. At F is a small cylinder having apiston G and a lion'- nectingrod H, also mounted on an eccentric I onits crankshaft This eccentric being a little in, advance of the crank orY degrees as shown in Fig. 6 At K is the exhaust port leading trfomcylin'der A into the open top of cylinder F. At L is the intake port forcylindenA and at M is shown an intake manifold leading from, anysuitable type of blower and carburetor. ,The operation of the engine isas follows; As the crank H reaches its ex trerne lowest ,position, theport L is opened and the port K is being closed by the piston G. Theport K ,is entirely closedbefore the port L closed. VWhilethe port L isstill open, the blower introduces the gaseous vapor into the cylinderand as the .pistonpomes up, the vapor is compressed andthen fired and asthe piston travels down, the exhaust port is opened before the intakeport is op ened, but when the port L does open, the blowerintro er maincylinder, closed and opened by movements of the small piston; a wallintermediate the superposed main cylinders passing a hollow piston rod;said hollow rod having a head as a piston for the upper cylinder andwith the base of the hollow rod rigid to the top of the lower piston;and packing means around said hollow rod; said hollow piston rod havinga port in the rod and a ball valve mechanism in the head of the upperpiston and an exhaust port near the base of the upper cylinder,

in testimony whereof I aflix my signature.
